Product Introduction

24-28KW Stainless Steel Heat Exchanger Solutions for Home Heating and Hot Water Condensing Gas Boilers

Introduction & Key Advantages

What Is a Condensing Stainless Steel Heat Exchanger?

A condensing stainless steel heat exchanger is designed to recover the hidden heat energy contained in flue gas vapor. During operation, it cools the vapor and converts it into liquid condensate, allowing additional heat recovery and improving overall heating efficiency.

It can achieve 107–109% thermal efficiency, compared with traditional heating systems that typically operate at 85–95% efficiency.

Key benefits include:

• Improved energy utilization
• Reduced fuel consumption
• Lower operating costs
• Enhanced heating system efficiency

Where Is It Used?

Key Advantages

1. Much Higher Efficiency — Saves Money

· Thermal efficiency: 107–109% (vs. 85–95% for ordinary boilers)

· Less gas used for the same heat output

· End users pay less on their energy bills

2. Stainless Steel — Built to Last

· Made from stainless steel

· Handles acidic condensate (pH 3–5) with no problem

· No rust. No corrosion. No leaks.

· Expected service life: 15+ years

3. Low Emissions — Clean & Green

· Meets EU ErP Directive and all major global environmental standards

· Helps customers stay ahead of tightening regulations

4. Smart Design — Better Performance

· Spiral finned tube structure increases heat transfer surface by 40–60%

· Multi-pass water circuit design for stronger turbulence and better heat exchange

· Low water resistance — works with smaller pumps → saves electricity

5. Quiet & Stable

· Smooth flame, no pulsation

· Quiet operation — suitable for homes and hospitals

· No hot spots → no cracking, no breakdowns

6. OEM & Custom Service Available

· Standard sizes in stock for quick delivery

· Custom design & tooling to match your specific boiler model

· Full technical support: heat load calculation, product selection, testing

· Your brand logo can be applied (OEM/ODM welcome)
